SAFE OR VAULT WALL.

T 0 all whom 2'75 may concern Be it known that I, CARL BARTELS, acitizen of the United States, residing at Hamilton, Butler county, Ohio,have invented certain new and useful Improvements in Safe or Vault 1Valls, of which the following is a specification.

This invention pertains to improvements in the construction of safes orvaults whose walls are formed of unmachinable metal, such as manganesesteel, the improvements relating particularly to the joints between theedges of the wall-plates.

The invention will be readily understood from the following descriptiontaken in con-V nection with the accompanying drawing in which Figure 1is a perspective view of portions of two abutting wall-plates whosejoint of union is secured by an embodiment of my improved system: Fig. 2a horizontal section of the same in the plane of line a of Figs. 1 and3: and Fig. 3 a vertical section of the same in the plane of line b ofFigs. 1 and 2.

In the drawing :1, indicates one of the wallplates, with a vertical edgeagainst which the edge of a companion plate is to abut: 2, the companionplate with its edge against the edge of the first plate: 3, the joint ofseparation between the two plates, the illustration showing thecontacting surfaces of the edges of the plate at this joint as beingplain, this being a form of plateedge which may be produced in goodshape in unmachinable method by process of grinding: 4, studs projectingintegrally from the interior surfaces of the plates, at each side of thejoint and near the joint: 5, a bar of machinable metal extending alongthe inner surface of plate 2 and having its inner edge overlapping plate1, this bar 5 being secured to plate 2 by having studs 1 passing throughapertures in the bar and then riveted so as to secure bar 5 rigidly toplate 2: 6, a similar bar similarly secured to plate 1 and having itsinner edge in engagement with the inner edge of plate 5: 7, the joint ofseparation between bars 5 and 6, this joint being upon a bevel, asindicated, so that the inner edge of bar 5 hooks under, so to speak, theinner edge of bar 6: 8, plates disposed against the inner faces of bars5 and 6: and 9, screws passing through plates 8 and screwed into bars 5.

Specification of Letters Patent.

Application filed March 3, 1913.

Patented June 3, 1913. Serial No. 751,699.

The plates and the bars having been properly formed, the bars are to besecured to the plates by riveting the studs 4, it being understood thatwhile the metal of the plates and studs is unmachinable it may beriveted, thus permitting the bars to be rigidly secured to the plates.Plates 8 are then to be secured to the bars by the screws 9, it beingunderstood that the bars are machinable metal which may be drilled andtapped to receive screws 9. The plates 8 may be of any desired length,even as long as the bars, though my preference is that they becomparatively short and applied to the bars at intervals as illustrated.The overlapping of plate 5 upon plate 1 serves in preventing theexistence of a straight passage through joint 1 to plates 8, and it alsoprovides a rabbeting for the positioning of the plates while in processof erection, and the beveled character of joint 7 serves in maintainingthis positioning during erection.

A safe or vault structure having been completed in the shape with itswall joints formed in the manner indicated, the structure may bedisassembled by removing screws 9 and plates 8, and when the parts areto be finally assembled the plates of the structure are to be placed inproper relationship, the overlapping of bar 5 upon plate 1, and thebeveled character of joint 7 serving to maintain the plates in properrelationship while plates 8 are being applied.

I claim 1. A safe or vault wall comprising, plates of unmachinable metalhaving their edges in abutting contact and having their inner surfacesprovided with integrally formed studs near the joint between the edgesof the plates, a bar of machinable metal secured to the inner surface atthe edge of each plate by means of said studs being riveted in holes inthe bars, a plate disposed against the inner surface of said bars, andscrews passing through the last mentioned plate and screwed into thebars, combined substantially as set forth.

2. A safe or vault wall comprising, plates of unmachinable metal havingtheir edges in abutting contact and having their inner surfaces providedwith integrally formed studs near the joint between the edges of theplates, a bar of machinable metal disposed against the inner surface atthe edge of one plate and overlapping the other plate and secured to itsplate by means of said studs eing rivet d in hole in the ar, a ba imachinable metal similarly secured to the other plate and having itsinner edge'in contact with the inner edge of the first=men1 tioned bar,a plate disposed against the inner s r ace of s d bars, an ws Pas ing 1through the last-mentioned plate and screwed into the bars, combinedsubsta-n-i faces provided with integrally formed studs hear e jointbetween the edges e the tially as set forth.
